I'm having trouble installing the latest Intel® Core™ Processors with Intel® HD Graphics on my laptop. Every time i try to install, during the installation an error pops up. It says "The setup program failed to install one or more device drivers. Setup will exit." What i'm trying to install is "Intel® Graphics Media Accelerator Driver, Windows 7* 64, Windows Vista* 64 (exe)" version 15.22.58.64.2993 which is the latest version, but every time i try to install it i get the error. So then i try installing the previous version 15.22.57.64.2827, but i still get the error.

So far i've tried to solve this error by disabling signature verification on windows and also tried installing the driver in Windows Test Mode, i still get the error.

It is possible you had a HP customized driver on your laptop . When an OEM installs a customized driver, it will block the installation of generic drivers. Keep in mind that with the generic driver you loose whatever customizations HP added to their driver. Usually customizations are for things like screen brightness settings, power management, resolutions supported, and various other things specific to your laptop. If you loose any functionality with the generic version you can always download the latest from the HP support site to restore the customizations.
